I paid the money for the Nissan setup and am thankfull that I did. when you buy the 7-pin, it comes with a relay plug/cable that you need in order for the brakes to work on your trialer. Plus, you will need to get the brake adapter that you can wire it into the brake controler and then just plug it into your truck. I think Nissan charges about $57 for the 7-pin, plus about $10 for the adapter plug. You will have to buy the brake controller seperate, but you will be so happy.
Oh one more thing. It is so stupid easy to install, dont pay anyone to do it. Some one posted picks of the whole thing on this web sight. The relay is just in front of the door jam of the passanger door at your feet...and it just pluggs in.
